Low voltage (1.3V-4.6V) reset circuit with manual reset and watchdog in SOT23-5 - Ultra-Low Power
The EM6323 and EM6324 are low power, high precision reset ICs featuring a manual reset and a watchdog inputs. They have different threshold voltages and several timeout reset periods (tPOR) and watchdog timeout periods (tWD) for maximum flexibility in the application. EM6323 has a manual reset (/MR with internal pull-up) and a watchdog input pins. EM6324 has only a watchdog input pin (WDI). The watchdog function can be disabled by driving WDI with a three-state driver or by leaving WDI unconnected. This is useful when the MCU is in sleep mode. Small 5-pin SOT23 package as well as ultra-low supply current of 3.8/m/A make the EM6323 and the EM6324 an ideal choice for portable and battery-operated devices.
